Australia completed a series whitewash over West Indies with a comprehensive 162-run victory in the fifth ODI.

Mitchell Johnson took five wickets as the Windies could only reach 172 in reply to Australia's 341 for eight, after Luke Ronchi, brothers David and Michael Hussey and Andrew Symonds all helped themselves to half centuries.

Shawn Findlay (59 not out) was the only player to pass 50 for the hosts, with Shivnarine Chanderpaul (38) the only other batsman to make any significant headway against a relentless Australia attack.

Chasing a challenging target, West Indies made a dreadful start by losing Marcus Gayle (five) in the second over, the opener thick-edging Johnson to Ronchi.

Ramnaresh Sarwan (seven) fared little better against the paceman as he was caught by a leaping James Hopes at mid-off in the sixth and Shane Watson trapped Xavier Marshall lbw for 17 to leave the Windies teetering on 56 for three.

Chanderpaul injected some much-needed life into the innings before skying Michael Clarke into the hands of Brett Lee at long-off.

Findlay steadied the ship but Dwayne Bravo's dismissal - caught by David Hussey at long-on off Symonds - sparked a collapse. Andre Fletcher made only one before he was stumped off Clarke and Denesh Ramdin followed the next over when he was caught by Michael Hussey off Symonds for three.

Findlay continued to push on and made his second one-day 50 with a single, but it became a one-man effort as the wickets tumbled.

Johnson picked up his third wicket, bowling Daren Powell (10) comprehensively in the 36th over, and then grabbed a fourth to send Nikita Miller in for eight.

The bowler wrapped up the comfortable win - and his five-wicket haul - by taking the wicket of Fidel Edwards.
